I think they flow around 260 on the intake stock. Try the KRC website.

Tried KRC and Hughes - plenty of smallblock cyl head flows but no 5.7 Hemi.
Anyone seem weblinks to 5.7 or 6.1 Hemi cylinder head flows? |

from some deeper Google searching:
quote: Published hemi heads 2.00 int 1.55 exh @ 28" You can see that the exhuast is where time needs to be spent int exh w/o pipe .100 74 52 .200 144 111 .300 210 146 .400 251 160 .500 265 164 .600 267 166 stock 65 cfm @.100 lift 28" 144 @ .200 214 @ .300 250 @ .400 262 @ .500 265 @ .600 268 @ .700 269 @ .800 Mild port similar to a stage 1 68cfm @ .100 lift 28" 144 @ .200 222 @ .300 270 @ .400 293 @ .500 300 @ .600 304 @ .700 310 @ .800 The hemi head is good, and once they crack the PCM, they are going to be tuff to compete with. end quote ----- link at http://www.ls1gto.com/forums/printthread.php?t=32427 about three quarter way down the threads ----- also some highly technical but interesting porting and flow discussion: http://www.eng-tips.com/viewthread.cfm?qid=92513&page=5 |
